How to check backup or restore time completion

We may have different way to check completion time Backup/Restore databases using DMV's

I have simple query here.

SELECT

              percent_complete  AS [Completed (%)]

              ,command  AS [Activity]

              ,start_time  AS [ActivityStartTime]

              ,d.name  AS [DatabaseName]

              ,DATEADD(MS,estimated_completion_time ,GETDATE()) AS [TotalTimeRemaining]

              ,(estimated_completion_time /1000/60) AS [RemainingTimeInMins]

              ,(estimated_completion_time /1000) AS [RemainingTimeInSecs]

FROM sys.dm_exec_requests r --ER

INNER JOIN sys.databases d  --sd

ON r.database_id  = d.database_id

WHERE command  LIKE '%RESTORE%'

OR command  LIKE '%BACKUP%'

AND estimated_completion_time  > 0

GO
